Abstract:

Remote sensing (RS) and Geographic Information System (GIS) are used to evaluate the flood risk zone. This paper is based on understanding of various recent trends techniques used in flood mapping to know the flood risk and vulnerability. In this regard, studied the various literature articles where in some of them proposes, multi-criteria, hydrodynamic, and various AI models and its techniques and frequency models. With these models we are able to evaluate the expected flood risk zone. Flood maps and digital elevation models (DEM) can be derived with satellite data which is helpful for decision making. The effective use of suitable technique and implementation of flood management strategies resulting in reduced flood impact. Remote sensing and GIS is a mechanism for finding flood risk mitigation plans.
